Article Title: Application of an advanced steerable microcatheter for challenging arterial embolization in massive hemoptysis
doi: 10.21037/jtd-2025-815
Figure Lengend Snippet: A case of hemoptysis due to pulmonary carcinoma. (A) Preoperative computed tomography angiography showing the tumor-supplying arteries (arrowheads). (B) Prior coil embolization (arrowheads). (C) Acute angulation (<30°) between the thyrocervical trunk (thick arrowheads) and subclavian artery (thin arrowheads). (D) Steerable microcatheter tip angulation (arrowheads). (E) Postembolization angiography confirming the success of the procedure. Delayed angiography after embolization to confirm the absence of collateral regurgitation (arrowheads).
Article Snippet: Subsequently, by using the SwiftNINJA ® steerable microcatheter (SSM) (Merit Medical, South Jordan, UT, USA), we accessed the responsible artery and successfully performed embolization.
Techniques: Computed Tomography
